About Interactive Brokers
Founded by Thomas Peterffy — a pioneer of electronic trading — Interactive Brokers grew from a market-making firm into a global brokerage built on automation and low costs. Its core platform, Trader Workstation (TWS), is a professional-grade terminal offering advanced order types, algorithmic execution, and risk tools, complemented by the lighter IBKR Desktop, mobile apps, and a full API for automated trading. IBKR is regulated across major jurisdictions including the SEC and FINRA (US), the FCA (UK), and others, and is well capitalised with a strong balance sheet.
